I live in the Philippines and one night after a looooong day distributing relief goods to the Taal eruption victims, we pulled over in a Starbucks to get some coffee and keep ourselves awake on our drive home. I ordered a drink and asked the barista to use soy milk instead because my stomach does this crazy protests with dairy. When I got my drink, the barista apparently put a sticker on my cup. It’s a sticker of a cartoon version of green carton of milk with “SOYMILK” written on it. What does this one mean? It’s my first time to ever see a sticker like this on my cup.

PS
I love stickers! I find it cute, I stuck it in my phone case. I am just really curious, I just really wanted to find out if the stickers are normally done.
